I've tried to read all 25 pages of this thread, but that is a bit to read.

Couple questions:

In his video he just swapped the engines out, and adjusted velocity using the reg on the fly. Is this a completely acceptable way to swap engines? Or should you use a pressure tester to verify pressure first, THEN swap engines?

When you buy the Ripper V-Com, does the other engine come with a back cap, or do you have to order that separately? Again, watching the video he was able to just swap and go without a lot of to do about it.

And in the efficiency video, why did they switch barrels towards the end? Not that this will throw off the efficiency test much as they didn't adjust down their increased FPS to even gain more efficiency, but I'm just more curious than anything on this point.

I ordered the bolt for my Ripper so I can tell you: No, it does not come with the back cap. You have to swap the cap from your current engine, which is only 2 bolts and takes less than a minute. just don't lose the o-ring between the two pieces.

I believe the barrel was switched because of the ice buildup. When shooting that much in the cold barrels tend to get icy and it causes barrel breaks.

The Lpr pressures for both systems are the same. So that is an acceptable way to change

The Spool bolt does NOT come with a back cap. You can however order one. I believe someone said it ran them about 40 dollars
